Sayfa 281 - These pats, to satisfactorily pass the requirements, shall remain firm and hard and show no signs of distortion, checking, cracking, or disintegrating.
Sayfa 281 - F. as practicable, and observed at intervals for at least 28 days. (c) A third pat is exposed in any convenient way in an atmosphere of steam, above boiling water, in a loosely closed vessel for five hours. 23. These pats, to satisfactorily pass the requirements, shall remain firm and hard, and show no signs of distortion, checking, cracking, or disintegrating.
Sayfa 274 - Texas, when tested in the gas producer and gas engine, have shown unexpectedly high power-producing qualities, such as promise large future developments in those and other States. (5) Some of the American coals, and the "slack" produced in mining these coals, can be briquetted on a commercial basis.
Sayfa 281 - Pats of neat cement about three inches in diameter, one-half inch thick at the center, and tapering to a thin edge, shall be kept in moist air for a period of twenty-four hours.
Sayfa xl - The Proceedings of the Society, and such papers or abstracts as may be approved by the Council, shall be published as soon as possible after each annual meeting. 9. AMENDMENTS. — This Constitution may be amended by a two-thirds...
Sayfa 273 - The members of the special committees on concrete and reinforced concrete of the American Society of Civil Engineers, the American Society for Testing Materials, the American Railway Engineering and Maintenance of Way Association, and the Association of American Portland Cement Manufacturers met at Atlantic City, NJ, on June 17, 1904.
Sayfa 275 - ... president or some other representative of each society be appointed to serve on the national advisory board for the investigation of fuels and structural materials. . In response to this invitation a meeting was held in Washington, DC, June 3, 1905, in the office of the Director of the United States Geological Survey. Later the personnel of this board was slightly changed, and in March, 1906, the members received direct appointments from President Theodore Roosevelt.
Sayfa 205 - experimenters are born, not made." He should keep constantly in mind the end to which his experiments tend, and understand clearly the effect of every step in the progress of his tests, and its influence on the final result. Above all, he should be a thinker. No man who, when a problem is presented to him, simply searches his memory for whatever he may have learned in the schools, or have perchance picked up in his reading, which bears on his problem, has any especial call to be a testing engineer....
Sayfa 281 - SCREEN). A. Proportions and conditions. — Proportions to be stated by weight and volume. The unit of volume for cement is 100 pounds per cubic foot. The typical Portland cement is to be prepared by thoroughly mixing a number of brands, each of which must meet the following requirements: Specific gravity, not less than 3.10. Fineness, residue not more than 8 per cent on No. 100 nor 25 per cent on No. 200 sieve. Time of setting: Initial set, not less than 30 minutes; hard set, not less than 1 hour...
